O A TTORNE 1 5 UNITED STATES PATENT OFFICE.

FRANK HATTON, OF PORTERSVILLE, CALIFORNIA.

TIRE-REMOVER.

To all whom it may concern:

Be it known that I, FRANK IIATTON, a citizen of the United States, residing at Portersville, in the county of Tulare and State of California, have invented a new and useful Tire-Remover, of which the following is a specification.

This invention relates to devices employed for removing tires from wheels, and has for its object to produce a simply constructed and efficient device of this character, which may be adjusted to fit wheels and tires of var1ous sizes.

With these and other objects in view which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction as hereafter fully described and claimed.

In the accompanying drawings forming a part of this specification and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

In the drawings :Figure 1 is a side elevation, and Fig. 2 is a front elevation, of the improved device. Fig. 3 is a transverse section on the line 33 of Fig. 2. Fig. 4 is a perspective view of the stop plunger, detached.

The improved device comprises a stock 10, preferably with means such as bolts 30 for attachment to a support, such as a post 31, or a wall or the like, the stock being of sufficient size to withstand the strains to which the device will be subjected.

The stock 10 is provided with spaced guides 1112, intermediate thereof, and also provided with spaced guides 1314 near the other end and spaced from the guides 1112.

The stock 10 is provided with a recess 15 between the guides 1112 and 1314, the guideway between the guides 1314 being in alinement longitudinally of the stock, and with the recess as represented in Fig, 2, whereby a shoulder 16 is formed near the inner ends of the guides 1112.

The inner faces of the guides 11-12 and 1314 are undercut or, dove-tailed, as indicated in Fig. 3, and respectively fitting these dove-tailed guideways are plungers 1718, the plun er 17 having a transverse head 19, and the plunger 18 having a transverse head 20.

It will be noted by reference toFig. 2 that Specification of Letters Patent.

Application filed April 23, 1906.

Patented March 17, 1908.

Serial No. 313,347.

the two plungers 1718 with their heads 1920, do not come in alinement longitudi nally of the stock 10. The head 20 of the plunger 18 designed for bearing against the tire, represented at 21, and the head 19 of the plunger 17 designed to bear upon the felly, re resented at 22, of the wheel, as representec in Fig. 1.

Extending from the stock 10 above the guides and the plunger 17 is a stud 23, upon which a cam 24 is mounted to swing, and adapted to bear upon the plunger 17, and operate the same.

The lunger 18 is provided with a plurality oi transverse a ertures 25 to receive, one at a time, a holcing pin 26, by which means the plunger may be adjustably supported in its guides 1314.

The plunger 17 is also provided with a stop 27 over the cam 24, to prevent displacement thereof, and the cam is provided with a socket 28 to receive an operating handle 29 of suitable len th, to enable the requisite force to be app Iied. By this simple means when a tire is to be removed the wheel is supported with its tire 21 within the recess 15 of the stock 10 and bearing a ainst the shoulder 16, and the plunger 18 adjusted by means of its spaced apertures 25 and pin 16 until its head 20 bears against the tire.

The cam 24 is then actuated by its handle 29, causing the plunger 17-19 to bear with sufficient force against the felly 22 to force the latter free from the tire. In operating the device the tire is forced for a short distance from the felly at one point, and the cam released and the wheel rotated to another point, and the cam again operated to force another portion of the tire a short distance from the felly, and so on around the wheel, repeating the action until the felly is forced free from the tire.

The stock 10, its shoulder 16, and the spaced guides 1112, and 1314, are cast in one single piece.

The implement is simple in construction, can be inex ensively manufactured, and of any requirec strength and size, and operates effectually for the purposes described.

Having thus described the invention, what is claimed as new is A tire remover comprising a stock having its intermediate portion provided with a transverse stop shoulder defining a reduced extension, spaced under cut guides secured to the reduced extension, a relatively stationary plunger engaging the under cut walls of the guides and provided with a transverse head adapted to engage the tire for forcing the latter in contact with the stop shoulder, spaced guides extending longitudinally of the upper portion of the stock and ofl set with respect to the lower guides, said upper guides terminating short of the adjacent end of the stock to form a seating recess and having their inner faces under cut, a relatively movable plunger engaging the under cut edges of the u per guide and provided with an enlargec head adapted to bear against the telly, an eccentric pivotally mounted in the seating recess and provided with an operating' handle, a strap secured to the upper plunger and bearing against the eccentric, there being a plurality of transverse recesses formed in the lower plunger, and a pin eX- tending through one of said openings and bearing against the adjacent ends of the lower guides for locking the head of the lower plunger in engagement with the tire.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two witnesses.
